A kind of slime that only inhabits the Zipangu Region. In the same way as other slime family monsters, they have flexible bodies and can change into various forms. Out of all the slime monsters they are especially proficient in mimicry. They can form clothes that look and feel almost like the real thing. They usually go with a kimono, but they can make any clothing as long as they’ve seen it before. They use this ability to try to pass themselves off as human women, but since the clothing they make is always wet it’s normally easy to see through it.
For that reason, it is said that they only show themselves in front of humans on rainy days. They appear near human settlements, highways, etc., standing dimly in the rain, gently smiling at men who pass nearby. If, thinking that they’re human women, the man returns the smile and calls out to them, then they end up recognizing the man as their husband and chase after him for the rest of his life. If the man attempts to flee then they’ll sense the presence of his spirit energy and follow him no matter where he goes, so it’s impossible to successfully escape them. Eventually, they’ll even turn up at a man’s home. Once she arrives at the man’s home, she’ll just start living there and behaving like his wife. Then she’ll cover him with her damp, wet, liquid body, having sticky sex, and milk his semen.
Perhaps because they’ve evolved and adapted in the Zipangu environment, which has comparatively many docile and devoted monsters, even though they are slimes which fundamentally have low intelligence, the knowledge and techniques necessary to perform household chores as a man’s wife is imprinted in their instinct. In this way they can skillfully and briskly take care of their husbands.
Also, they start to make their clothes according to their husband’s desires. During semen milking they appear different from basic slimes which mate with hunger and lust. Somehow, it seems that there is devotion and service. In the same way as other members of the slime family, the number of individuals is increased through division. In the case of an ordinary slime, having just been born, the little slime’s head would be full of thoughts of hungrily gorging on semen, but as for the nureonago, it is said that even after just being born they’ll help their mother with the housework, having devoted behavior.
